Hi,

Could you try to turn off the option "Use bootstrap" in Configuration > Display ?

Hi, and thank you for your answer, but "use bootstrap" was already turned off.
I found the origin of my problem : it is because i use the plugin "jfusion" which logs me on 2 Joomla website at the same time. if I deactivate its "user" extension, the problem disappear.
Do you think there is a hack i can use to solve my problem, cause I need jfusion?
thank you.

Hi,

It looks like an issue with output buffering where an extension is clearing too much or now enough the buffers it opens. It's hard to track down.
I don't see why JFusion would do that and I don't know the code of JFusion at all. The best would be to ask them.
